2. Outline • PAC Applications in Near Future • Technical Features for Coverage • Application Examples • PAC Functions • Summary

3. PAC Applications in Near Future Internet of networked objects All connected & interactive world Convergence of real & virtual world • Most devices and mobile terminals are connected via IP protocols • Information is exchanged through the interconnections of the devices • Integrated services with virtual and real lives Merged into PAC applications Smart Driving Social network services • In-Building Searches for services and users • In-Campus Speed Limit Localized networking services Distance : 5m Caution Advertisement with augmented reality PAC Services w/o infrastructure Local information services with location guide services

4. Technical Features for Coverage Coverage and Distributed Coordination 1 Km • MIMO/Beamforming for PAC 1.6 Km • KAIST (<2 km) • Commercial District (<1 km) User Device Wi-Fi Direct PAC (long range) PAC (short range) 2.6 Km~ • Cheong Gye River in Korea Kangnam District in Korea Cheong Gye River in Korea Campus (KAIST) • Communications for PAC • One-hop coverage : ~ 1 km • Multi-hop support: ~3 km • Coverage extension with MIMO/Beamforming

5. Applications in Close Proximity • Applications • game, wireless display, chatting, and data (e.g. pictures) sharing, • Technical requirements • Easy connection setup and fast service initiation • Direct communications without coordination • Group communications • Multimedia streaming • High speed data transmissions

6. Applications with Location Information • Applications • Route navigation in a district • Narration services in a museum • Experiences of sample video and audio clips in a shop • Technical requirements • User or service recognition with profile matching • Information broadcastings • Advertisements with personalized information – coupon, mileage • Location tracking with high precision

7. Applications with Traffic Offloading • Applications • Large volume of data transfers, and social network services • Technical requirements • Direct traffic transfer without infrastructure network • Distributed wireless resource management

8. PAC Functions • Key Features • Coverage extension • multi-hop, MIMO, beamforming, routing protocol and addressing • High precision location services • Time of Arrival • High speed ( ~ 50 Mbps ) throughput • MIMO, minimized MAC operation overhead • distributed wireless resource scheduling policy for throughput improvement • Power management support to save energy consumption • Sleep mode operation, Idle mode operation • Group Communications • Group management for group creation, joining and deletion

9. Summary • We need to define functional requirements for the PAC applications • We will provide our considerations for practical parameters of the PAC applications
